Abstract:
An active matrix liquid crystal display assembly including a flex circuit (48) for interfacing substantially all of the row and column address lines of the display panel (40) with a display output controller. The flex circuit is preferably made of two planar sheets laminated to one another, the first flex circuit sheet interfacing the row address lines with the display output controller and the second sheet interfacing the column address lines of the active matrix with the controller. The flex circuit includes a plurality of extension members (61), each extension member being electrically adhered to a driver tab mounted to a peripheral side of the display panel.
Abstract:
A curved array ultrasonic transducer is manufactured by cutting a flat transducer plate (12), which is attached to a flexible support plate (11), into a plurality of segments (14), the segments being hingedly attached by the support plate. The support plate is bent to a radius (FIG. 2) and the conductive traces in a flexible circuit board are electrically connected to the transducer plate segments (FIG. 4). The flexible circuit board, having a plurality of branches, is bent to a perpendicular position such that the traces in the plurality of branches become substantially aligned (FIG. 6). The traces exiting the branches are then electrically connected to a pin and socket connector device (FIG. 8).
Abstract:
A cathode ray tube has a thin flexible circuit (48) comprising one or more films of polyimide with a plurality of conductive tracks deposited directly thereon for establishing electrical connection between a multi-pin leadthrough (45) passing through the wall of the tube's envelope (31) and terminals of electrically operable components within the envelope, e.g. electron gun (35) and beam-deflection electrodes (36,39 and 40). A number of track-carrying films may be stacked together to form a laminate structure. Such a flexible circuit avoids outgassing problems and, being thin and flexible, occupies minimal space and is easily routed around internal components to ease assembly
